I have pynq 2.3 running in my Ultra96 board, and I’m having difficulties using USB cameras with OpenCV. (I tried using 2 cameras which worked fine with Raspberry Pi and my Laptop running Linux)
I also tried running the examples in the PYNQ Computer Vision library, and the funny thing is that, sometimes a frame is obtained from the camera and the rest of the code works, but when I run it again it fails to capture an image.
Is this a software issue? Both cameras are USB 2.0 devices. Maybe the PYNQ distribution only supports USB 3.0 devices? Because before I changed the OS to PYNQ, I tried running opencv with my cameras on the linux build that was already flashed to the sd card, and everything worked fine.
If I’m unable to get pynq working, can anyone provide me any documentation/tutorials where I can use the other linux build to accelerate image processing?
